- IMPROVEMENT IN HORS-E HAY-FORKS.

TO WHOM IT MAY CONCERN: Y l

Be it `Known that I, MARY JANE LAIRD, of Middletown, in the county of Dauphin, State of Pennsylvania, being administran-ix on the estate of ANDREW J. LAIRD, latte of said Middletown, who invented and put in use an important improvement to his hay-fork, patented August 21', 1866, do hereby declare the following to be at, full and exact description of the same, reference being had to the drawings that accompany and form a, part of v these specifications. v

Figure 1, perspective view ofk hay-fork with guard attached.'

Figure 2, hay-fork with the guard, showing the position of the lever when raising the hay.

Figure 3, View of guard, showing the form or shape.

Letter A, ring or loop, to whjh the hoisting-rope is attached; letter B, shank or bars, sustaining the` tines end lever; letter C, lever` by which the tines or blades are operated; letter D, guard, to protect the lever C.

The object of this invention is to protect the end of the lever, where it projects through the ring A, from striking against anything while raising the hay, and thus unshipping the loed before you desire to.

The upper part of the lever C,-it will be seen,'is a horizontal arm, tvhich projects through the ringA when the tines are in position to lift the hay, as seen in fig. 2. Thedrawings will, perhaps, suiiiciently show the manner of construction. It is made in .the form of' three braces, united in the centreas shown in iig. 3. The two upper ends nre riveted, one on each side, near the top of the ring A, and the other" end tothe shank or bar B. I

What is claimed, and desired to be secured by Letters Patent, is-

The guard D, when applied to hay-forks for the protection of the lever or arm, substantially as described und set forth. l g I In testimony whereof, I have signed my name to this speciication in the presence of two subscribing witnesses.
